Electronic Ground

Near equilibrium potential energy and dipole moment functions have been calculated for the electronic ground state of the XeH+ ion from highly correlated SCEP/CEPA electronic wavefunctions. The following spectroscopic constants for 132XeH+ are obtained:Re= 1.611 ± 0.005 Å, ωe = 2313 ± 50cm-1, ωexe = 41 ± 5cm-1 and D0(Xe+ + H) = 3.90 ± 0.1 eV.Infrared transition dipole matrix elements and probability coefficients for 132XeH+ and 132XeD+ are given. The electric dipole moment functions of the protonated rare gas atoms HeH+ to XeH+ are discussed.

Binary Collisions

A theory of the line shape for collision-induced translational absorption in rare-gas mixtures is developed. The reduced line-shape function is expanded in terms of the quantity ρ/σ, typically of the order of 0.1, where ρ is the range of the induced dipole moment and σ is the size of the repulsive core of the interatomic potential. The calculation is based on the special properties of the exponential model for the induced electric dipole moment. The temperature is assumed to be sufficiently high that the motion of the atoms can be treated classically, while the density is assumed to be sufficiently low that only binary collisions are important and intercollisional correlation effects are negligible over the frequency range of interest. A least-squares comparison of theory with experiment yields values for ρ and the magnitude of the induced moment for Ne–Ar and He–Ar pairs.

The observed far-infrared collision-induced absorption of helium–argon mixtures is used to determine the parameters in an induced-dipole moment function of the form[Formula: see text]It is shown that, with this form of μ(r), the values of the constants μo, ρ, and c7 that are necessary to fit the first two moments of the observed absorption contour are in disagreement with the available theoretical values of these constants. Possible explanations for this disagreement are discussed in the paper. Finally, it is shown that if μ(r) were known, it is possible to obtain an excellent representation of the entire absorption spectrum from a knowledge of only the first three moments, which are easily calculated equilibrium quantities.
